FUEL VAPORIZER.

Application filed March 20, 1326 Serial No, 96,293.

The invention forming the subject matter of this application is designed for use on internal combustion engines to vaporize, as fully as possible, the heavier liquid fuel 5. distillates which ordinarily pass unvaporized from the carburetor into the combustion chambers of the engines.

As is well known in this art, the passing of unvaporized liquid fuel into the combus- H tion chambers of internal combustion engines results not only in a waste of fuel, with the consequent loss of power, but also results in objectionable dilution of the engine lubricating oil, with all the concomitant harm- 15 ful effects of such dilution.

In present day fuels for engines of this type, a great deal of the fuel ordinarily wasted can be utilized, instead of being wasted ininjuring rather than in operating the engines, if it can be heated, on its way from the carburetor to the engine intake, to a temperature sufliciently high to vaporize all or most of the fuel capable of vaporization. It is the main object of my invention to efiiect this desirable vaporization, and to utilize every particle of liquid capable of being used, with the consequent gain in power and diminution in wear of the engine and its parts. 7

A further object of the invention is to utilize the exhaust heat, which is ordinarily wasted, to effect this desirable additional vaporization of liquid fuel.

A still further object of my invention is to provide a vaporizer which can be readily attached to any internal combustion engine, and in which the parts thereof may be readily separated and assembled to facilitate cleaning, renewal or repair.

Other objects concerned with the manner of applying the vaporizing heat to the fuel, and with the various structural features of the instrument, will appear more fully in the following detailed description taken in connection with the accompanying drawing,

in which:

Figure 1 is an axial vertical section through the fuelizer or vaporizer; and

Figure 2 is a section on the line 2-2 of Figure 1.

The instrument comprises an-outer casing 1, preferably cylindrical, having flanges 2 and 3 extending laterally outward from the top and bottom edges thereof, respectively,

and also having a flanged fuel inlet pipe 4:

extending tangentially from the side thereof. A perforated inner casing 5 is supported concentrically Within the casing 1 by flange 6 at the .top thereof resting-on the flange 2 of the outer casing l, the two flanges being suitably secured together as by the bolts 7 A fuel inlet pipe 8, extending tangentially from the casing 5, fits snugly within the pipe 4; of the outer casing to serve also as an'additional positioning support for the inner casing. The pipe 8 terminates in aflange 9 adaptedto be bolted or otherwise secured, along with the flange 10 of the pipe 4, to any suitable conduit (not shown) lead ing from the carburetor.

Resting on top of the flange 6 and also secured by the bolts 7 i to the flanges 2 and 6 is a wide flange 11 of a conical cap 12 which terminates in a neck 13 adapted to be secured by its flange 14; to the fuel in- 1 take of the engine.

The casing 5 is closed at its upper end by a plate 15 integral with the flange 6, and this plate 15 is provided with a series of segmental apertures 16 circularly arranged around the center of said casing. The apertures 16 are formed by stamping down parts of plate 15 to form segmental deflecting plates 17 which are inclined in the direction of the arrows (Figure 2) to deflect the heavier particles of liquid fuel downwardly toward the bottom of the casing 5. Any desired or necessary number of apertures 19 are formed in the casing 5 to permit the heavier particles of fuel whirling around in the casing 5 to pass by centrifugal force into the space 20 between the casings 1 and 5 and to fall by gravity onto the vaporizing hot plate 21. i

The plate 21 is provided at its center with a conical heating member 22 arranged concentrically within a frustro-conical heating conductor 23,- which opens at its bottom into the heating chamber 24:, and at its top opens into and extends somewhat into the conical cap 12. The conductor 23 is suitably heat insulated from the casing 5 as by the lagging 25.

- In order to provide the vaporizin heat, a heating pan 26 is formed with a flange 27 adapted to match with the flange 3 and to be secured thereto, with the plate 21 clamped therebetwe, by any suitable means such as the bolts The heating pan 26 is also provided. "t-h n et an outlet conductors 29 and 30, respectively, adapted to be connected by any suitable system of conduits to the engine exhaust.

In operation: It will be apparent that as 'fuel is sucked into the casing 5, by suction deflected by the plates 17 downwardly toward the bottom of the casing 5, will be also thrown by centrifugal force, set up by the vortex, through the apertures 19 into the space 20, whence they will fall into the vaporizing chamber 24 and onto the vaporizing plate 21.

The liquid fuel in the chamber 24 is boiled and vaporized by contact with the hot plate 21 and the cone 22, and the vapors thereof ascend through the conductor 23 into the cap 12 to mix therein with the cooler vapors passing directly through the apertures 16 and to pass therewith directly to the engine intake. I

It will be apparent from the drawing that the several parts of the invention may be readily assembled and" disassembled whenever it becomes necessary to clean, renew, or repair the parts thereof, and the invention as a whole is of the extremest simplicity.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is .1. A liquid fuel vaporizer comprising a cylindrical casing; a drum of smaller diameter than said casing concentrically mounted therein and having its cylindrical wall per-' forated, the top of said drum having a central aperture and a series of segmental deflector plates stamped down to form a circularseries of segmental apertures concentrio with said central aperture, the bottom of said drum having a central aperture larger than the central aperture in the top, a frusto conical conduit joining said central apertures and projecting beyond the central aperture in the top; a heating chamber connected to said casing andhaving the top thereof spaced below the bottom of said drum; a mixing chamber connected to said casing above said drum, and a feed pipe extending through said casing into said drum. i

2. A liquid fuel vaporizer comprising a casing, a drum mounted concentrically in said casing and having its cylindrical wall perforated and spaced from said casing, the top wall of said drum being provided with stamped down deflector plates to form a circular scries'oi segmental apertures concentric with the axis of said drum, a trust-oconical conduit extending axially through the top and bottom of said drum and tapering inwardly from said bottom to said top'; a fuel teed conductor extending through said casing tangentially into said drum; a heating chamber connected to said casing-and spaced from the bottomof said drum; and a mixing chamber connected to said casing above said drum. 2 i

In testimony whereof I have signed my name to this specification.
